South Korean President Orders Comprehensive Probe into Ballot Paper Shortage Disrupting Recent Local Elections

South Korean President Lee Jae-myung has ordered a joint prosecution and police investigation into a ballot paper shortage that shut down voting at roughly 50 polling stations during the June 3 local elections, according to Reuters. The crisis erupted when actual voter turnout hit an estimated 61% — far outpacing the National Election Commission's (NEC) printing threshold of just 50% of registered voters.
The NEC chairperson and secretary-general have already offered their resignations. Protests drew between 10,000 and 50,000 people in Seoul on June 6, with some demonstrators demanding a full revote. President Lee called the incident "hard to accept" and said the explanations given so far were "insufficient."
The shortage traces back to a quiet rule change the NEC made after the 2022 elections. Seeking to cut waste from unused ballots, the commission lowered its minimum printing threshold from 60% to 50% of registered voters per district. On June 3, that gamble failed badly.
Turnout surged to an estimated 61% — 11 percentage points above what the NEC had printed for. In districts like Songpa-gu and Gangnam-gu in Seoul, and Geomdan New Town in Incheon, polling stations simply ran out of ballots mid-day. Voting halted at around 50 locations nationwide. Some stations extended hours to 10:00 PM to let emergency ballots arrive.
The fallout was immediate and physical. In Seoul's Jamsil 7-dong neighborhood, protesters blocked authorities from removing two ballot boxes for counting. That standoff lasted 35 hours. Riot police were deployed at dawn on June 5 to clear the blockades.
Large "Revote Rallies" filled Seoul streets on June 6. Police estimated 10,000 protesters near Olympic Park; organizers put the figure at up to 50,000 at Gwanghwamun plaza. Pastor Jeon Kwang-hoon, a protest leader, framed the shortage as a "rigged election" — a charge the government rejects as baseless.
The ruling Democratic Party of Korea (DPK) won 12 of 16 major governorships and mayoralties. But the People Power Party (PPP) — the main conservative opposition — said the vote was "contaminated" and "invalid." PPP floor leader Song Eon-seok demanded re-elections in the hardest-hit districts. The Korean Bar Association called the shortage a violation of "universal suffrage," and constitutional petitions have already been filed by voters who were turned away.
The ballot shortages hit hardest in traditionally conservative districts like Gangnam and Songpa, where Election Day — rather than early voting — is the preferred time to vote. That pattern gave opposition leaders a potent "voter suppression" argument, even as the NEC insisted the crisis was pure incompetence, not intent.
President Lee is doing two things at once. He ordered the joint investigation and called for a parliamentary probe. He also asked for "fundamental institutional reforms" at the NEC — potentially ending its status as a fully independent body that cannot be audited by the executive branch. Lee said the right to vote is "a constitutional right" and that the NEC's failure "gravely undermined the foundation of popular sovereignty."
At the same time, Lee nominated Han Seong-sook — former CEO of Naver, South Korea's biggest internet company — as Prime Minister. The move is seen as a bid to stabilize his administration and shift focus toward economic growth and AI policy. If investigators find the ballot shortage was intentional rather than accidental, courts could invalidate results in specific districts and order unprecedented local re-elections later in 2026.
